FILLING-SEVERING DEVICE FOR LOOMS.

Application filed April 30, 1913. Serial No. 764,480.

W. This invention relates particularly to looms provided with automatic filling supplying mechanism, and has for its object the production of means for insuring the cutting of the weft or filling thread at a predetermined point close to the selvage and between itvand the point of attachment of the end of the filling. In looms provided with such filling severing devices it is important that the end of the incoming filling should be severedas soon as possible, otherwise the filling may be broken and the end snapped into the fell and woven into the cloth causing a defect, Various devices have been designed for securing a prompt severance' of the filling and the object of this invention is to present a construction by whichthe desired result maybe simply andaccurately secured.

In this invention a filling catching device is mounted on the lay and projects upwardlyabove the run of the incoming filling. This device is adapted to yield forwardly or toward the fell upon contact with said filling so that upon the backward movement of the lay after replenishment the device yields and passes behind the filling and then on the succeeding beat-up carries the filling into the field of operation of the usual severing dev1ce.

The nature of the invention will appear more fully from the accompanying description and drawing and will be particularly pointed out in the. claims.

The drawings illustrate.only so much of an automatic filling replenishing loom as is necessary to an understanding of the present invention. 3

In the drawings :Figure 1 is a plan view showing a portion of the loom frame, lay, filling feeder and filling severing means sufficient to illustrate in connection therewith the present invention. Fig. 2 is a front elevation showing a portion of the lay and shuttle box with the device of this invention Specification of Letters Patent.

in place, Fig. 3 is a view partially in cross section of-the construction shown in Fig. 2 enlarged and showing a preferred form of the filling catching device of this invention.

The loom frame, breast beam A, supplying mechanism, including the feeder to receive the filling carriers such as the bobbins supported from the weft or filling end holder 6 the lay A the hopper stand H, the

shuttle box S the shuttle binder B, the" I temple T, and their associated parts are all familiar and well known in automatic filling replenishing looms of this type, and need not be described in detail, not being specifically involved in this invention.

The filling severing means 1s mounted in a fixed position adjacent the fell and selvage, for example in the patent to and as shown Lussier, 1,012,875 granted December 26, 1911, is commonly mounted on the temple. In the drawings, the cutting blade is shown at C with its PIOJGCtlIlg ends 0 and c 1 When the filling is beneath the ends 0 and c it is within the field of operation of the severing means and will be severed thereby, This invention is, not concerned, however, with the particular form of the severing means;

When a fresh filling carrier has been inserted in the shuttle by the operation of the automatic filling, changing mechanism, and the shuttle thrown across the lay A the end of the filling twill lead frointhe selvage of the cloth to ,the filling end holder 6 as shown in full line in Fig. 1, and. as the lay beats forward toward the breast-beam this filling end is intended to be caught and severed by the severing means, but owing to a of fabric woven, the force required to beat the filling into the fell, the extent of the bump of the cloth,

variation in the character theposition of the-temple and other causes, the, severing means frequently fails to sever the filling promptly.

This invention provides a filling catching device constituted as a finger mounted on the lay, and projecting -upwardly above the run of the incoming filling t and this finger is adapted to yield forwardly or toward the breast beam or fell upon contact with the run of *fillingJ Upon the backward movement of the lay after replenishment this finger yields as the filling comes against it, the filling rides over it and the finger returns to its upright position this time in beat-up the finger carries ward and insures its passing 1nto the field the rear of the run of filling so that on the succeeding the filling well forof the operation of the severing device.

In the specific-form of construction illustrated as a preferred embodiment of the invention a bearing plate 10 is secured as by screws 11 to the front face of the lay and carries at its upper end about level with the raceway alined bearings '12 in which is mounted a shaft or pin 13. The filling catching device or finger is formed ofthin metal and is indicated at 14. At its lower end this finger 's split vertically, one section being bent to orm a bearing sleeve 15 surrounding the shaft or pin 13, while the other section 16 depends below the shaft and constitutes a stop abutting against the plate 10 and limiting the rearward movement of the finger so as to maintain it in a substantially vertical position. The body of the finger 14 is curved slightly transversely so as to present a slightly convex surface against the filling at the rear of the finger. A spring 17 surrounds the shaft 13 and abuts at one end against the plate 10 and at the other end against the finger 14 thus serving normally to maintain the finger upright. This spring is delicate so that the finger readily yields as the filling comes against it and passes beneath the filling.

It will thus be seen a very simple construction insures the filling on the second pick after replenishment being brought into the field of the severing device. In the drawings the dotted line position indicates the position to which the filling will be carried by the filling catching device upon the second beat-up after replenishment. v

1. In a loom provided with automatic filling supplying mechanism, the lay, a severa fresh supply of filling mounted adjacent the selvage, a filling catching device mounted on the lay and projecting upwardly above the run of the lncoming filling and adapted to yield forwardly or toward the fell upon contact with said filling, whereby upon' the backward movement of the lay after replenishment the said device yields and passes behind the filling eration of the severing device.

2. In a loom provlded with automatic filling supplying mechanism, the lay, a seyering device for the end of'a fresh supply of filling mounted in fixed position adjacent the selvage, a finger pivotally mounted on the lay between said mechanism and said severing device, a stop to limit the rearward movement of said finger on its maintain it in vertical position, a spring normally holding the finger against said stop but permittirigi 't to yield forwardly e filling, whereby'upon replenishment the said device yields and passes behind the fillingandon the succeeding beat-up insures the filling being carried into the field of operation of the severing device.
